CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 474,225, dated May 3,1892.

Application filed October 27, 1891. $erial No.409,9 31. (No model.)

T0 at whom it may concern:

Be it known that I, CYRUS S. DEAN, a sub ject of the Queen of England,and a citizen of Canada, residing at Fort Erie, in the county oflVelland, Province of Ontario, Canada, have invented certain new anduseful Improvements in Car-Heaters; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to heaters for vehicles, especially of that classwhich are designed to travel overland and which are readily accessiblebeneath the floor from the outside, such as street-cars, omnibuses, andother vehicles of a similar nature. The casing or shell which receivesand supports the removable fire-pot is pendent from the floor of thevehicle and forms a hot-air chamber and receives the cold air, which isheated in its passage therethrough by the heat radiating from thefirepot and the smoke-fines, the heated air escaping into the vehiclethrough a suitable register. The fire-pot is removably inserted througha door in the front end of the casing and is adapted to automaticallyform a close joint with the smoke-fines, by means of which the productsof combustion are carried off to a suitable conductor, which conveysthem to a convenient point of discharge into the open air. By having thefire-pot removable the fire can be started therein in a barn at aconvenient point along the road, and after the heavy smoke has passedoff and the coals thoroughly ignited the pot can be placed in the case,thereby obviating the annoyance and the destruction which would followif the fire was started in the heater on the vehicle. Moreover, thedanger from fire is lessened, because when a vehicle is turned in thefire can be removed therefrom.

The improvement consists of the novel features and the peculiarconstruction and combination of the parts, which will be hereinaftermore fully described and claimed, and which are shown in the annexeddrawings, in which- Figure 1 is a perspective view of the heaterdetached, the door of the casing being open. Fig. 2 is a perspectiveview of the fire-pot detached and the front end of the smoke-t1 ues,

the latter being separated from and arranged in a relative position tothe said pot. Fig. 3 is a longitudinal section of the heater, showingits relative position to the vehicle to whlch it is applied. Fig. 4 is atop plan view of the heater, the top of the casing and the top of thefire-pot being removed.

The heater comprises, essentially, a casing or shell A and a removablefire-pot B, the latter being provided with a bail O for convenience ofhandling. The front or receiving end of the casing is deeper than therear portion to accommodate a fire-pot of suitable proportions, in whichthe coal will have a proper depth and body. The rear portion D of thecasing or shell is comparatively wide and shallow, being designed toform, in effect, a supplemental hot-air chamber, and is provided in itstop side with opening cl, through which the heated air escapes andenters the vehicle through the register E.

The register-frame E overlaps an open ng in the vehicle-floor incoincident relatio n w1th the opening cl, and has a depending portlon e,which connects with the top of the shell or casing and surrounds theopening d and. forms a conductor to convey the hot air from the saidshell or casing to the vehicle. E, which pass through the horizontalportion of the register-frame E and through the easing, hold the saidparts in place and support the rear portion of the said shell or casing,the front portion of thelatter being suspended from the vehicle by meansof the bolts f. To prevent overheating the vehicle-floor directly overthe heater, the latter is suspended at a distance from the door, leavingan a1r-space between the top of the heater and the under side of thevehicle-floor, the distance being fixed by the vertical portion 6 of theregisterframe and by spacing-blocks or short tubes f, mounted on thebolts f.

The fire-pot B is removably inserted through the front end of the casingor shell and is supported by means of lateral projections 12, extendedfrom the sides of pot B, resting upon ribs 0., projecting inward fromthe inner sides of the said shell or casing. The front end of the casingor shell is closed by door G, which is held shut by any suitablefastening means, as the latch g. The stop h, carried by the door G, isadapted to press against the door The bolts Ice H of the fire-pot andhold the latter closed, and at the same time hold the fire-pot withinthe shell.

To allow for variation in the mechanical construction of the parts ofthe heater, the stop h is adjustable, so that it can be set to effectthe desired result-21 6., hold the door H closed and prevent movement ofthe firepot within the casing. The projections I) serve to maintain afixed relative distance between the sides of the fire-pot and the sidesof the casing and prevent lateral shifting of the said fire-pot.

The opening i in the front side of the firepot opposite the ash-pitadmits air to the fire to support combustion, and also serves as aconvenient means to permit the removal of the ashes and cinders.

The grate I is movable and is adapted to be actuated by means of theshaker-bar J, which is pivoted at one end to one side of the firepot andhas its other end extended through an opening in the other side of thesaid firepot to be engaged by a poker or other suitable instrument forpurposes of shaking the fire. This bar J has engagement with the gratebetween its ends, so as to move the said grate when actuated.

The conductor K for carrying oif the products of combustion is locatedin the rear portion of the shell or casing, and is preferably composedof a series of smoke-fines, which are united at their ends by thesmoke-boxes L and M. The smoke-pipe N for carrying off the products ofcombustion to a convenient point connects with the smoke-box L.

The smoke-box M is adapted to connect with the fire-pot by a slip-joint.The flanged opening in the rear side of the fire-pot matches with acorresponding flanged opening in the smoke-box M, the former slippinginto the latter as the fire-pot is thrust into place within the casingor shell.

It will be observed that the fire-pot and the smoke-conductor aresurrounded by an airspace,in which the cold air is heated, the airentering through the open end of the enlarged portion of the said shellor casing.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A heater comprising a casing having the front portion comparativelydeeper than the rear portion and having said rear portion wide andshallow and constructed to have a register connected therewith, asmoke-conductor located in the shallow rear portion of the easing andcomposed of a series of pipes connected at their ends by smoke-boxes,and a fire-pot removably inserted in the front portion of the casing andadapted to automatically connect with the inner smoke-box of the saidsmokeconductor, substantially as described.

2. The herein-described heater, composed of a casing having a wide andshallow supple-.

mental hot-air chamber projected from its rear, a smoke-conductorlocated in the said hot-air chamber and composed of a series of pipeswhich are connected at their ends by smoke-boxes, a firepot removablyinserted through the front end of the casing and suspended therein bylateral projections on the fire-pot engaging with ribs on the sides ofthe casing and adapted to connect automatically with a smoke-box of thesaid smoke-conductor, and a door to close the open end of the casing andprovided witha stop to hold the door of the fire-pot closed and preventthe latter from shaking about, substantially as described.

3. In acar-heater, the combination, with the casing having ribs a on itsopposite sides and having its front end open, of a fire-pot adapted tobe thrust through the open end of the easing and having lateralprojections which engage with the ribs a and support the pot and preventlateral movement of the same, and having a bail and provided with a doorin its front side and a door to close the'open end of the casing, andhaving an adjustable stop to engage with the fire-pot door and hold itshut and prevent longitudinal movement of the said fire-pot within thecasing, substantially as described.

at. The hereinbefore shown and described car-heater, consisting of acasing having its front portion deeper than the rear portion and havingthe said rear portion wide and shallow and constructed to have aregister connected therewith, a smoke-conductor located in the shallowrear port-ion of the easing, composed of a series of pipes which areconnected at their ends by smoke-boxes, a firepot having a bail andprovided with lateral projections and adapted to be thrust through theopen end of the casing and be supported therein by the lateralprojections engaging with ribs on the sides of the casing, and a door toclose the open end of the casing and provided with an adjustable stop tohold the fire-pot door closed and prevent the said firepot fromlongitudinal movement in the case, substantially as described.

In testimony whereof I am): my signature in presence of two witnesses.
